Claude Opus 5, Now Live In Terminal X

Anthropic's Claude Opus 5 is now running in Terminal X. Anthropic positions it as an everyday model that comes close to the frontier intelligence of Claude Fable 5 at half the price, and reports state-of-the-art results on coding and knowledge-work evaluations. In our own grading of Opus 5 across live analyst queries, we saw a meaningful gain in reasoning and answer clarity in financial workflows.

The gains that matter to an investment team show up in numerical work and in long-running agentic runs. Anthropic's early-access finance testers report a step up on hard financial-modeling tasks: 9 percentage points higher accuracy on average across effort levels, with a third fewer turns and tool calls and 60% less time. Anthropic's applied AI team cites numerical reasoning, table work and sharper critical thinking on financial research workflows.

Independent evaluation points the same direction. Vals AI, which runs private finance benchmarks built with industry practitioners, placed Opus 5 first on CorpFin v2 at 73.19% and first on Finance Agent v2 at 58.63%, both proprietary test sets covering filings comprehension and end-to-end analyst tasks.

Terminal X is model-agnostic by design. Our Agent Orchestrator selects the optimal model and reasoning depth at each step of a workflow, so Opus 5 slots into the pipeline where its strengths compound: parsing a Private Data Room during diligence, reconciling projections against actuals in filings, holding a thesis together across a long multi-agent run, and producing the final deliverable at the end.

At Terminal X, we've found that a benchmark score isn't the last mile. Models alone can't produce industry-standard work, because no model knows which vendor feeds matter to your desk, how your team structures an IC memo, or where the real numbers live across twenty systems. Terminal X FDE's close that gap. If you're interested in integrating Terminal X across your firms entire internal knowledge base, reach out to us for a pilot at [email protected].
